Can anyone please give me a good starting point for spring weights (in lbs) used for a full-race GT40?
My project isn't a GT40 but a car with similar configuration. I know the spring rate will only be a starting point and I will have to play around with rates etc once I get the car on a track. That is a long way down the line but I want to fit shocks/springs during the initial assembly to check locations/clearances etc.
Fully laden sprung weight. Shocks mounted 20 degrees from vertical:
Estimated 1149 lbs
(Ford GT40 1046 lbs approx) - 41.7%
(Ford GT40 45.8%; Ferrari P3 41.8%)
Estimated 1609 lbs
(Ford GT40 1240 lbs approx)- 58.3%
(Ford GT40 54.2%; Ferrari P3 58.2%)
Any thoughts on suitable spring rates in lbs as a rough starting point? What are racers currently using on the GT40?
The aim is to race the car against the cars it was designed to compete against in period - GT40 and Ferrari P3. The project is detailed here Jaguar XJ13 | Building the Legend
